Market Structure and Trading Volume
Posted: 13 Apr 2004
Historically, trading volume reported for NASDAQ stocks has been overstated vis-a-vis New York Stock Exchange (NYSE) stocks, due both to the dealer's participation in trades as a market maker and to interdealer trading. Beginning in 1997, the Securities and Exchange Commission (SEC) changed order handling rules and trade reporting rules, which may have reduced or eliminated the overstatement of NASDAQ trading. We examine trading volumes of firms changing from NASDAQ to the NYSE since 1997 and document that reported trading volume for NASDAQ stocks continues to be overstated. Moreover, the degree of overstatement is much larger for firms with high trading volume.
